METALLIC TIE FOR RAILROADS.

SPECIFICATION forming part of Letters Patent No. 722,373, dated March10, 1903.

Application filed September 22,1902. Serial N0.124,301. (No model.)

[0 all whom it may concern.-

Be it known that I, GEORGE HOWARD LYLE, a citizen of the United States,residing at Ben Avon, in the county of Allegheny and State ofPennsylvania, have invented or discovered new and useful Improvements inMetallic Ties for Railroads, of which the following is a specification.

In the accompanying drawings,whioh make part of this specification,Figure I is a perspective of a tie and rail fastening involvingmyinvention; Fig. II, a side elevation thereof, showing the road-bed insection along the center line of the tie, the ballast at one end beingomitted; and Fig. III, a perspective of a rail-holding clip of a formslightly different from that shown in the preceding views.

My invention relates to metallic ties for railroads; and its object isto provide a tie made of pressed steel or wrought-iron which will becomparatively light, exceedingly strong, and simple in its manufactureand application.

In the drawings, 1 is the tie proper, which consists of a strip of steelplate about six inches wide bent at each end as follows: The outer threeinches is bent up vertically to form the flange 2. About six inches fromthe flange 2 the plate has the vertical limb or upstanding portion 3,which is about five inches high. The top of the limb 3 is joined by theinwardly-extending top 4, which is about five inches long, or the widthof the flange of the rail 5 seated thereon. top 4 is joined by avertical limb or upstanding portion 6, parallel to-the limb 3 and havingthe same height. The limbs 3 and 6 and the tops 4 form benches or bases,which are connected together by the horizontal tie or or hole 12 toreceive the bolt 13, hereinafter referred to. The purpose of this blockis not only to support the weight on the tie, but also to preventlateral movement of the bench and to prevent any liability of thematerial in the space 9 flowing down unevenly under the por- The innerend of the tions 7 and S of the ties, as it might do under the vibrationdue to the passing of a large number of cars.

Any suitable filling material, as ordinary ballast 19, lies under thetie between the blocks 10 and covers the tie between the rails and theends thereof beyond the rails. ballast on the outer sides of the railsby engagement with the flanges 2 and the benches resist the lateralthrust or the bending of the ties. Under same conditions the spacesoccupied by the blocks 10 could be filled with ballast.

I may strengthen the meeting angles of the portion 8 and the limb 3 ofthe tie by means of the rib 14, pressed out to form a brace, as shown.This rib may be used with or without the block 10 or the ballast in thespace 9. It will probably be needed, if at all, only at the outer sidesof the benches, as shown on Fig. I, but may be used at the inner sidesthereof when necessary. Whether the ballast, the cement, or the rib willbe used alone or the latter will be used with the ballast or cement willdepend upon the strains the tie will be subject to.

The rails are laid on the benches transversely of the ties, as shown inFigs. I and II. To hold the rails on the benches, I provide for eachbench two clips, each having a vertical body portion 15, two verticalend flanges 16, and an inclined top flange 17. The top flange 17 of theclip is bent so as to fit the outer top portion of the flange of therail when the body portion 15 fits closely against the outer sides ofthe top portion of the limb 3 or 6. The body portions 15 of the clipsare as wide as the tie, and the end flanges are bent closely against theedges of the limbs 3 and 6 of the benches, the flanges preferablyterminating flush with the inner surface of the said limbs. A clip isplaced on each side of each bench, as shown in Figs. I and II, and theheaded bolt 13, having a nut 18, is passed through alined holes in thebench and the clips and secures the rail rigidly in its place on thebench. The clips may have the top flanges as wide as the tie, as shownin Fig. I, or as wide as the combined width of the body portion 10 andthe end flanges 11, as shown in Fig. III.

I do not limit myself to the precise dimen- The.

standing benches, each bend being continuous across the whole width ofthe tie, in combination with means for holding the rails firmly on thebenches.

3. A metal tie made of a plate bent near the ends into upstandingbenches, and strengthening-ribs at the angles of the benches, incombination with means for holding the rails 20 firmly on the benches.

4. A metal tie bent at opposite ends to form upstanding rail-supportingbenches, clips on the benches constructed to overlie the flanges 0f therails, and means for holding the benches and the clips assembled.

5. A rail-supporting base, and a clip secured to the side of the baseand having a flange lying on the rail-flange to hold the rail on thebase and end flanges lying against the 30 ends of the base to preventmovement of the clip.

Signed at Pittsburg this 19th day of September, 1902.
